Input ground motions for tall buildings with subterranean levels
• Core Group: J. Stewart, C.B. Crouse, M. Lew, A. Mikami, F. Ostadan, E. Taciroglu
• Report available for review

Guidelines for Modeling and Acceptance Criteria (ATC 72)
• Core group – J. Malley, G. Deierlein, H. Krawinkler, J. Maffei, M. Pourzanjani and J. Wallace• Approach: Workshop identified key issues, assignments to experts to develop principles,
procedures, and values.• Key issues:
– Good practices in nonlinear dynamic analysis (H. Krawinkler, G. Deierlein, J. Heintz)– Podium and basement modeling and performance characterization (J. Maffei, J. Malley)– Wall modeling and performance characterization (J. Wallace, M. Pourzanjani)

Building Pilot Studies• Core group: J. Moehle, S.
Mahin, J. Hooper, T. Yang, C. McQuoid, Tea Visnic
• Approach– Representative building
models– Variations in model
parameters– 100s of ground motions in
various M, r , etc. bins– Ground motion selection and
scaling tests
